Remove lines that match string at end of column
I have this:

Code:
301205          0000030000041.49000000.00                   2011111815505     908

301205          0000010000027.56000000.00                   2011111815505     3083

805223          0000030000049.65000000.00                   20120301203       8         
805223          0000030000062.73000000.00                   20120301203       15        
805223          0000030000057.45000000.00                   20120301203       33

I want to remove the lines that end with 30120 but only in the 3rd column (only marked red).

I tried these:

Code:
awk '$3 !~30120 ' rassales.txt > rassales2.txt

removed any 30120 in 3rd column not just lines ending with
Code:
awk '$3 !=30120 ' rassales.txt > rassales2.txt

only complete match (removed nothing)

Am I close?Smilie

Looks like it removed this too:

Code:
805223          0000030000049.65000000.00                   20120301203       8         
805223          0000030000062.73000000.00                   20120301203       15

I want to keep those
